Structure Your Prompts

[Subject] + [Action] + [Setting] + [Style] + [Camera/Technical]

Examples:

// Good: Specific, action-oriented
"A golden retriever running through autumn leaves in a forest, slow motion, cinematic, warm lighting, tracking shot"

// Bad: Vague, static
"A dog in a forest"

Workflow Examples

Production Workflow

// 1. Fast preview with Runway Turbo
const preview = await fal.subscribe("fal-ai/runway-gen3/turbo/text-to-video", {
  input: {
    prompt: "A woman walking through a rainy city street at night",
    duration: 5,
    ratio: "16:9"
  }
});

console.log("Preview:", preview.video.url);
// Review and refine prompt...

// 2. Final render with Kling Pro
const final = await fal.subscribe("fal-ai/kling-video/v2.6/pro/text-to-video", {
  input: {
    prompt: "A stylish woman walking confidently through a rainy Tokyo street at night, neon reflections on wet pavement, cinematic lighting, slow motion, tracking shot",
    duration: "10",
    aspect_ratio: "16:9"
  }
});

console.log("Final:", final.video.url);

Batch Generation

const prompts = [
  "A sunrise over mountains",
  "A sunset over the ocean",
  "A storm rolling in"
];

const videos = await Promise.all(
  prompts.map(prompt =>
    fal.subscribe("fal-ai/ltx-video", {
      input: { prompt, aspect_ratio: "16:9" }
    })
  )
);

videos.forEach((v, i) => console.log(`Video ${i + 1}: ${v.video.url}`));

Best Practices

1. Use subscribe() not run() - Video generation takes time
2. Start with previews - Use faster models to iterate on prompts
3. Be specific about motion - Describe what moves and how
4. Include camera direction - Guide the visual perspective
5. Use negative prompts - Avoid common artifacts
6. Match model to need - Don't use premium for tests
7. Include audio keywords - For models that support audio generation
